Abstract
According to one embodiment, a first substrate and a second substrate are pressed from an opposite surface of a joint surface of the second substrate such that a joint surface of the first substrate and the joint surface of the second substrate are in contact with each other. The second substrate is restrained by a member to provide a gap between the joint surfaces. It is determined, based on a temporal change of a joint interface calculated based on an image imaged from the opposite surface side of the joint surface, whether joining is normally performed.
